Constant Pressure Adjustment: There is a hole in the middle of the part. The high pressure in the bottle is injected into the constant pressure chamber through the hole. The constant pressure can be controlled by adjusting the distance between the part and the constant pressure gasket.
Constant pressure gasket: The function is to block the middle hole of the constant pressure adjusting bolt. The high pressure in the bottle passes through the middle hole of the constant pressure adjusting bolt, flows through the gap between the valve body and the constant pressure valve core and enters the core central hole. Finally, it reaches the air chamber. With the pressure increasing gradually, the constant pressure valve core is pushed to the direction of the constant pressure adjusting bolt. When the pressure reaches a certain value, the constant pressure sealing gasket connected with the valve core is tightly blocked. Hold the constant pressure adjusting bolt to achieve the goal of constant pressure.
One-way valve ball: This ball acts as a stopper when exhausting and prevents high pressure in the bottle from entering the gas chamber. When filling, open to let external high-pressure gas into the cylinder
Exhaust hole: This hole is used to eliminate the "breathing" gas flow caused by the rapid movement of the spring part of the constant pressure valve core.
Limit card: to prevent the constant pressure valve core from falling into the air chamber.
